Garage Door Perimeter Weatherstrip in Lorneville

A length of weatherstrip along the right jamb has pulled away, nails and all, and it slaps against the trim every time the wind picks up. The wood behind it is dark and soft where it meets the floor.

In plain words

The skill in this job is in the position of the fin. It should touch the door with a small, even deflection, so that it seals when the door is closed and springs clear as the door lifts. Set too far off, it leaves a standing gap; pushed too hard, it drags, folds under and tears within a season. The header piece goes on first, fastened from the centre outward so it stays straight, and the sides are fitted tight beneath it so the fins overlap at the corners. Fasteners are spaced evenly in sound wood, and any joint where water could get behind the stop is caulked.

Sound familiar?

Dry leaves keep appearing in the same corner inside the garage, and this fall there were mouse droppings along the wall beside the door. When you look, the corner where the top and side strips meet is wide open.

  1. 1

    Probing the jambs and header

    The strip is only as secure as the wood behind it, so the jambs are probed with an awl along their length and especially the lowest part, where slush and salt sit all winter. Soft, dark or crumbling wood is marked for repair. The header is checked for sag and for gaps opening between it and the top section. Where the jambs are clad in aluminum or vinyl, the technician looks for what the cladding hides and for where the seal can be fastened through to solid material. This step often adds a splice of new lumber or PVC trim to the job, and it is what makes the new seal stay put.

  2. 2

    Replacing the wood stop with a one-piece vinyl stop

    When the old wood stop is cracked, rotten or buried in paint, it is replaced rather than covered. The one-piece stop, a rigid vinyl moulding with the flexible fin formed along one edge, is cut on a mitre saw to header and side lengths and fitted the same way, header first. It needs no paint, does not rot, and its fin and stop are one part, so the seal cannot peel away from the moulding. Corners are either mitred or the sides butted tight under the header with the fins overlapped. The result looks like fresh trim and works as a seal.

  3. 3

    Before the freezing rain

    In late autumn, wipe the fin with a silicone spray or a silicone-based lubricant on a cloth. It leaves a film that cuts the odds of meltwater bonding the fin to the cold door face during an ice storm, though a hard freeze can still catch it. Oil-based products are avoided because they swell and soften vinyl over time. The same wipe once or twice through the winter keeps the fin supple. If the door does freeze to the seal, a little warm water along the edge from inside, or simply waiting for the sun, frees it without pulling; dry the thawed spot afterwards so it does not simply refreeze.

In the van

What affects the quote

  1. 1

    Weather on the day

    Cold weather means keeping vinyl warm between the van and the opening and fitting each length with extra care, so a winter visit can run a little longer than one in mild weather.

  2. 2

    Jamb material

    Wood jambs take nails; steel or aluminum-clad jambs need screws and sometimes a backing piece, and masonry openings need a different fixing altogether, each with its own time and hardware.

  3. 3

    Alignment work on the door

    Where the door sits out of square and a track bracket or the door itself needs small correction before the seal can meet it evenly, that adjustment is named separately.

Garage Door Perimeter Weatherstrip: questions

Advice · (249) 490-5342

How is the seal fastened to the frame?

A flexible fin is nailed or stapled to the face of the wood stop with galvanized or stainless fasteners spaced evenly along its length; a one-piece vinyl stop is nailed or screwed through its rigid edge into the jamb and header. Fasteners go into sound wood, heads are set flush without crushing the vinyl, and the joint between stop and trim is caulked where water could get behind.

How long does perimeter weatherstrip usually last?

It depends on sun, cold and how the door meets it. One manufacturer's guide suggests replacing seals every two to three years, while a well-set fin kept free of paint and wiped with silicone before winter often goes considerably longer. Rather than a calendar, watch the fin: when it stiffens, cracks or shrinks back from the door, it has done its work.

The wood around my door is rotten near the floor. Can the seal still go on?

Yes, and the rot is handled first. The soft wood at the base of the jamb is cut back to sound material and a new piece of lumber or PVC trim is spliced in, fixed and primed, so the fasteners for the new stop bite into something solid. This is one of the most common additions to a perimeter seal job here, because slush and salt sit against the jamb base all winter.

What the census means at the door

56%

Older homes. About 56% of homes in Kawartha Lakes were built in 1980 or earlier, according to the 2021 Census.

Extension springs are common on older doors, and they should carry a safety cable through the middle so a broken spring is held rather than flung. Adding those cables is a small job the technician checks for and offers on any older door he services.

84%

Mostly houses. Single-detached houses make up about 84% of homes in Kawartha Lakes (2021 Census).

Detached homes usually have their own driveway and apron, and years of freeze and thaw can leave the concrete uneven where the door meets it. A thicker bottom seal or a threshold strip closes the gap, keeping snow, leaves and cold air out of the garage.
